RESUMO
Objetivo: Reportar un caso clínico de hepatocarcinoma fibrolamelar metastásico y su manejo multidisciplinario. Caso clínico: Paciente de 24 años de edad con dolor abdominal, distensión abdominal y fiebre. Se le realizó tomografía computarizada de abdomen donde se encontró tumoración hepática irregular. Se realizó laparotomía con evidencia de múltiples implantes en cavidad abdominal y se diagnosticó mediante estudio histopatológico hepatocarcinoma fibrolamelar metastásico. Se decidió realizar citorreducción más quimioterapia hipertérmica intraperitoneal (HIPEC). La sobrevida de la paciente fue de 11 meses. Discusión: El hepatocarcinoma fibrolamelar es un tumor raro. Aún no hay consenso sobre el mejor tratamiento en pacientes con metástasis que tengan buena funcionalidad. El manejo actual se basa en la quimioterapia sistémica y la resección quirúrgica en casos localizados. En el caso de nuestra paciente, la cirugía citorreductora más HIPEC se realizó con la intención de mejorar la supervivencia. Se necesita más evidencia para definir esta estrategia como tratamiento estándar.
Aim: To report a clinical case of metastatic fibrolamellar hepatocarcinoma and its multidisciplinary management. Case report: 24 year-old patient with abdominal pain, bloating and fever. A computed tomography of the abdomen was performed; an irregular hepatic tumor was found. A laparotomy was performed with evidence of multiple implants in the abdominal cavity and the histopathology report was metastatic fibrolamellar hepatocarcinoma. It was decided to perform cytoreductive surgery plus HIPEC. The patient's survival was 11 months. Discussion: Fibrolamellar hepatocarcinoma is a rare tumor. There is still no consensus on the treatment of choice in patients with metastases with good functionality status. Current management is based on systemic chemotherapy and surgical resection in localized cases. In the case of our patient, cytoreductive surgery plus HIPEC was performed with the intention of improving survival. More evidence is needed to define this strategy as standard treatment.

BACKGROUND AND PURPOSE: The long-term survival of patients with peritoneal carcinomatosis of colorectal origin has been achieved with cytoreductive surgery, which removes all macroscopic implants, combined with hyperthermic intraperitoneal chemotherapy (HIPEC). The current technology for administering intraperitoneal heated chemotherapy is expensive and, for some institutions, unaffordable. We conducted this study to assess the temperature stability provided by a modified, inexpensive system, to offer a simple and low cost alternative to the standard HIPEC delivery equipment. METHODS: Ten patients with histologically diagnosed peritoneal metastases of adenocarcinoma or pseudomyxoma peritonei underwent cytoreductive surgery and received HIPEC with 5-fluorouracil for 90 min, delivered via our modified system. The temperature was recorded from two probes: one in the inflow catheter and one in the outflow catheter. The intra-abdominal temperature was monitored meticulously to maintain it at between 41 and 42 °C. RESULTS: All patients underwent cytoreductive surgery and HIPEC using our modified delivery system. Temperature stability was achieved in all patients, with a mean of 41.4°. There were no thermal injuries associated with any of the ten perfusions. The mean hospital stay was 15 days and the median survival was 30 months. CONCLUSION: Analysis of this data demonstrates that the uniform delivery of HIPEC at 41° with this modified system is feasible and safe. The outcome of the patients treated with cytoreductive surgery and HIPEC with this modified system compares favorably to other published series. Its low cost and simple design will give more patients with peritoneal carcinomatosis access to this treatment.

El objetivo de este artículo es ofrecer una revisión sobre algunas estrategias terapéuticas actuales para pacientes con carcinomatosis peritoneal (CP), la que históricamente ha sido considerada como una condición terminal, sólo susceptibles de tratamientos y cuidados paliativos; y ocasionalmente de qui-mioterapia sistémica aislada con mala respuesta y supervivencias promedio inferiores a los 6 meses. La combinación de cirugía de citoreductora (CCR), que implica peritonectomía y resecciones multiviscerales con hipertermia y quimioterapia intraperitoneal intraoperatoria (HIPEC), es un concepto relativamente nuevo en el tratamiento de la enfermedad microscópica residual intraperitoneal. La indicación de este método se ha ido extendiendo de forma progresiva, para pacientes con CP muy bien seleccionados; y tiene base en varios estudios de fase III, cuya conclusión es que se puede obtener suficiente citoreducción. Sin embargo, hasta el momento existe cierto consenso basado en la evidencia, en que estaría indicada en pacientes portadores de pseudomixoma peritoneal, mesotelioma peritoneal y cáncer colorrectal; y en CP de otro origen, dependiendo de cada caso en particular.
The aim of this article is to provide a review of some current therapeutic strategies for patients with peritoneal carcinomatosis (PC), which historically has been considered a terminal condition, only amenable to palliative care, and occasionally systemic chemotherapy alone with poor response and lower average survival. The combination of cytoreductive surgery (CRS), which involves peritonectomy and multivisceral resections and intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) is a relatively new intraperitoneal treatment of microscopic residual disease concept. The indication of this method has been extended progressively to highly selected patients with PC and it is based in several phase III studies, which concluded that it is possible to obtain sufficient cytoreduction. However, until now there is some consensus based on evidence, in which HIPEC would be indicated in patients with peritoneal PC originated in pseudomyxoma, peritoneal mesothelioma and colorectal cancer; and CP from another source, depending on each particularcase.
